WEIGHING-SCALE.

SEPECIFICATION forming part of Letters Patent No. 555,661, dated March3, 1896.

Application filed October 19, 1895. Serial No. 566,221 (No model.)

To all whom it may concern.-

Be it known that 1, AUGUST REBELsKI, a citizen of the United States,residing in the city of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful ImprovementsinIVeighing-Scales, of which the following is a specification.

This invention relates to an improved weighing-scale which combines theadvantage of a platform-scale with the facility of a spring-scale bypermitting the direct reading off of the weight of the article placed onthe scale pan or platform, and which has the fur- I ther advantage ofcertain features of construct-ion and combinations of parts to be fullydescribed hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved weighing-scale. Fig. 2 is a transverse section online 2 2,Fig. 1; and Fig. 3 is a front view of the indicator with the dial-plateremoved so as to show the motion-transmitting mechanism.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the base; A, an upright standardattached to the base; B, a horizontal bar that is attached to the upperend of said standard; C, the scalebeam that is supported on thehorizontal bar 13, and D the scale-pan which is suspended by means ofknife-edges from one end of the scale-beam O. The lower edge of thescalebeam 0 is made in the shape of an arc and beveled, said bevelededge moving in a corresponding groove 1) in the upper edge of thesupporting-bar B, so that when the scale-beam is oscillated under theaction of the weight it has a socalled rolling motion on the supporting-bar B. By means of the beveled lower edge of the rolling scale-beam,which edge is in the grooved upper edge of the supportingbar 13, thelateral shifting of the scale-beam is prevented, while the longitudinalshifting of the same is prevented by means of curved steadying-pieces b17 which are attached to and project upwardly from the ends of thehorizontal supporting-bar B and along which the ends of the scale-beammove by means of antifriction-rollers O, which are supported in sheavesor blocks attached by curved arms 0 to the ends of said scale-beam asshown clearly in Fig. 1.

The scale-pan D is suspended from that part of the scale-beam whichextends a greater length at one side of the standard A, while from theother end of the scale-beam C is suspended likewise, by means ofknife-edges, a weight E that serves to counterbalance the weight of thescale-pan. The weight E may be suspended directly from the shorter partof the scale-beam C, or it may be applied to an arm 6 that is suspendedloosely below the supporting-bar B in a keeper 6X of the same and in thelower part of a yoke C suspended from said shorter part of thescale-beam, said arm being made in two sections, which are connected bya ring-shaped portion 6, through which passes the upright standard A, soas to move freely without interfering with the movement of any part. Thescale-beam 0 passes through an opening a in the upper end of thestandard A, said opening being large enough so that the scale-beam movesfreely therein without coming in contact with the standard. To the bar Band at the upper end of the standard A is applied a supporting-arm F, onwhich the indicator G is supported. The dial of the indicator isgraduated in pounds and fractions of pounds, according to the size ofthe Weighingscale. The pointer g is moved over the face of the dial bysuitable transmitting-gear, which gear is connected with the shorter endof the scale-beam O and consists of a fixed arm g attached to thescale-beam, an arm 9 supported in a sleeve 9 of the same and capable ofadjustment in said sleeve by means of nuts g a link g pivoted to the armg extended into the casing of the indicator and pivoted to the eccentric9 which acts on a pivoted finger g that rests on said eccentric andserves to operate a rack that is guided between two pairs ofantifriction-rollers, said rack g engaging a pinion g on the shaft ofthe pointer, as shown clearly in Fig. 3. In

place of the transmittinggear described any other well-known mechanismcan be employed by which the section of the scale-beam can betransmitted to the pointer so as to read off gradually from the dial theweight of the article placed on the scale, as I do not confine myself toany special construction of transmitting mechanism.

Before using the scale the weight is adjusted so as to counterbalancethe scale-pan. The pointer is then adjusted to zero on the dial by meansof the adjusting-nuts g of the transmitting mechanism. \Vhen this isaccomplished the scale is ready for use. It will instantly andaccurately (accuracy is, as well known, missing in spring-scales)indicate the weight of the article placed in the scale-pan, and withoutthe putting on or shifting of weights as in beam-scales.

My improved scale is adapted for commercial as well as domesticpurposes, as it plainly and quickly indicates the weight of the articleplaced on the scale-pan without the inconvenience of the beam or springscales heretofore in use.

Having thus described my invention,I claim as new and desire to secureby Letters Patent I. A weighing-scale, composed of a horizon talsupporting-bar, an oscillating or rolling scale-beam supported on saidbar, steadying devices applied to the ends of the bar and beamrespectively for preventing the longitudinal shifting of the beam, ascalepau suspended from one end of the beam below the supporting-bar, acounterbalancing-weight suspended from the other end of the beam belowthe supporting-bar, an indicator provided with a graduated dial and arotary pointer, and mechanism connecting the shorter end of thescale-beam with the arbor oi the pointer oi the indicator, substantiallyas set forth.

2. A weighing-scale, consisting of a horizontal supporting-bar, anoscillating or rolling scale-beam supported on said bar, curvedsteadying-pieces applied to the ends of the supportingbar for guidingthe scale-beam and preventing the longitudinal shifting thereof, ascale-pan suspended from the longer part of the beam, acountcrbalancing-weight suspended from the shorter part of the beam, anindicator, and transmitting mechanism between the shorter part of thebeam and the arher of the pointer of the indicator, substantially as setforth.

In testimony that I claim the foregoing as my invention I have signed myname in pres ence of two subscribing witnesses.
